Welcome to the Microchip SAM9G46 and SAM9M11 Cryptographic Peripherals – Part One product training module. The SAM9G46 and SAM9M11 eMPUs correspond respectively to the SAM9G45 and SAM9M10 with the addition of cryptographic peripherals such as the AES, TDES and SHA. This presentation will define the basic terminology and introduce the concepts of cryptography. There will be a review of the two basic types of data encryption, with a comparison of the advantages and disadvantages of both.
